RADIATOR CONSTRUCTION.

Application filed April 7,

To all whom t may concern:

Be it known that l, FRANK A. MERRELL, a citizen of the United States, and a resident of Malden, county of Middlesex, State of Massachusetts, have invented an lmprovement in Radiator Constructions, of which the following description, in connection with the accompanying` drawing. is a specifica tion, like characters on the drawing representing` like parts.

This invention'relates to improvements in radiators and the general objectthereof is to provide a radiator construction comprising' a heating section and a conduit integral with said heating1 section havingat its ends means for connecting the conduit into a rise-r of the heating system thereby avoiding the necessity of the usual piping and elbows required to connect the riser to the radiator. By the'present invention the radiators can be more readily assembled in the heating system, the sizes and types of fitting; simplified, and the cost of construction and installation greatly reduced.

A further object of the invention is to provide a novel radiator section which can be assembled with standard radiator sections for the purpose above stated.

A further object of the invention is to provide radiator sections which may be employed either in a one pipe steam system, in which the steam and Water of condensation may be introduced and delivered. through the 'saine valve, or aradiator scc- `tion which Will permit the introduction of the heating fluid atrthe top and the discharge thereof at the bottom, or radiator sections `which may be employed in a tivo `pipe system in which the heating fluid is introduced intoV one section and delivered from another through' conduits integral with the respective sections adapted to be connected into and form parts of the supply and return risers respectively.

A further object of the invention is to provide radiator sections of the character above described in which any suitable type of valve, either manually or automatically operable, may be employed.

Other objects and features of the invention Will more fully appear from the follovvingr description and the accompanying drawing` and will be particularly pointed out in the claims. j j l preferred embodiment of the invention itself.

Fig. 2 is a vertical longitudinal sectional view cfa preferred form of radiator soo-- tion embodying;` the invention adapted to be used either in a one pipe or tivo pipe systenig and,

lfig. 3 is a vertical longitudinal sectional vieiv of another type of radiator section having a thermostatieally operated valve for` controlling the discharge of the heating` fluid into the return riser of 'the heating' system.

The invention as illustrated in Fig. 1 comprises a radiator l having),` end sections 2 and intermediate sections 3 which may be ot a standard type and also having an intake section fi and an out-let section 5 enr bodyinrfa preferred form of the invention. The intake section et, which is illustrated in vertical section in Fig. 2, comprises a heat radiating section or loop G of any desirable length having in its sides upper and loivcr nipples 7 and 8 to communicate with other juxtaposed sections of the radiator which may be and preferably are of a standard type. The intake section 4t is provided with an integral conduit 9 which extends longitudinally of the heat radiating section 6 and portions l0 and ll of the Wall of Which preferably are common to both the heat radiating` section and the conduit. @esirably a space l2 is provided intermediate of the sections l() and ll to permit circulation of air through the radiator. The conduit 9 desirably is upon the back side of the radiator and the projection from the rear face of the radiator thereby rendered inconspicnous. j

The opposite ends of the conduit 9 are provided With coupling` means by which the conduit may be connected directly into a riser for the heating),` tluid to form a continuous partofthe riser.

Bly reason of this construction the usual piping and elbows, required to connect the radiator to the riser, are eliminated as the conduit 9. forms a direct part of the riser As illustrated the upper end portion of the conduit 9 is provided with an externally screw threaded boss 13 which is cona nected by an expansion joint lll, such as a corrugated copper joint, to the section 15 of a supply riser' leading' to an upper story in the building in which the radiator is installed, while the lower end of the conduit 9 is provided with an internally screw threaded boss 1G which receives and is coupled to the upper end of a lower section ll' of the supply riser for the heating` fluid.

The heating section of the radiator is provided with an extension 18, the wall of which is integral with that of the conduit 9 and a suitable port 19 in this integral wall provides a passage for the heating fluid into the heat radiating section.

Any suitable manually operated or automatically operated valve may be provided to control the flow of heating' fluid from the conduit S) into the heating section (i. As illustrated a member 20. forming` 'a valve seat. screwed into the wall of the apen ture and is provided with two or more diametrically disposed sectors :2l with corresponding' apertures therebetween. 'lf he stein 2Q of a suitable valve having' sectors correspondin-Q` to the sectors of the valve seat, is rotatably mounted in or upon the central portion of the valve seat and the valve is held seated by a helical spring; 24, surrounding' the valve stem and abutting at one end against the valve stein and at its other end upon a flanged head Q5 which is screwed into a suitable opening' in the front of the extension i8 of the radiator section. The valve stein Q2 is suitably hushed and is provided with an actuating handle 26 by means of which the valve opening may7 be controlled.

In the present construction the heating' fluid from the conduit 9, therefore, enters the heatine section 6 through the regulatine` valve and thence passes throue'h the nipples 7 of the other radiator sections and returns through the lower nipples Fl to a section having' suitable means for deliverine' the spent heating` fluid to a return riser of the heating system.

A preferred form of outlet section 5 is illustrated in 3 and comprises a heat radiating' section 27 preferably corresponding;` in form to the adjacent standard radiator units and having' an integral conduit f evtendine longitudinally thereof, the end sections of the conduit havino'common walls 29 and 30 with the heat radiating' unit, with an l.atermediate space 31 between the walls of the heatingl section and the conduit to permit the circulation of air. The conduit 2S desirably is at the rear of the heating` section and is straight and adapted to be connected into and form a part of the return riser. The ends of the conduit are provided with means for connecting' the conduit directly into the riser to form a part thereof.

fis illustrated the i-inper end of the couduit 28 is provided with an internally screw threaded boss 32 which is connected to an upwardly extending section 33 of the return riser. The lower end of the conduit is pro vided with an externally screw threaded boss B-l adapted to be coupled to the downwardly extending' section 35 of the return riser.

The heating' section 27 is provided with a downward extension having' anA openine at its front to receive a screw threaded thinned cap 37 which forms a seat for a valve which preferably is operated by a bellows 38 containingl an expansible l'lnifl.

valve 39 secured to the bellows is positioned to engage a valve seat 4170 having a screw threaded exterior portion which encomplementary screw threads in an aperture in the common wall BO of the Conduit and heating' section.

ln the operation of the radiator illustrated in Fir. l the heating` fluid enters through the riser 17 and conduit, 9 which forms a part thereof, thence passes throue'h the valve-controlled opening in the upper portion of the intake section into the heat radiating' section G, from which it passes through the nipples .7 progressively through the radiator sections and returns through the nipples S of the radiator sections to the outlet section 5, from which it passes into the extension 3G and the condensate accumulates around the thermostatic bellows 38 of the valve 39, thereby cooling` the expansible fluid contents of the bellows and causing the bellows to contract and remove the valve 39 from its seat. thus permitting' the condensate to escape into the return pipe.

lt will, of course,y be understood that any other forms of valves may be employed than those illust-rated herein and that automatr cally actuated valves controlled thermostatically, or in any suitable manner, may be. provided for controlling` the admission into the heat radiating; units and that any suitable type of valve. either manually or automatically operated, may be provided for permitting the heatingr fluid to escape into the return riser. It will also be understood that the radiator may be, employed upon any type of heating` system to which it may be adapted, such as7 steam? vapor or hot water systems.

A further feature of the invention consists in providing a radiator section which may be employed either in a two pipe sys tem as disclosed. or in a single pipe system. llVhere a single pipe system is employed the construction illustrated in Fig. 2 may be used by merely inverting the radiator section thereby admitting steam through the valve, which is at the lower end of the heating section. and permitting the condensate to run out through the same valve.

In all of these constructions the conduit desirably is straight and extends longitudinally of the heat radiating section so that it may be connected directly into the riser of the heating system in such a manner as to form a continuous part thereofrlhe radiator sections above described, comprising the heat radiating section and the conduit, may be readily cast from iron, or other suitable metalJ as an integral unit and obviously may be made of any desired form corresponding to the standard radiator sections with which it is to be associated, or special constructions may lif desired be made.

It will, therefore, be understood that the present embodiment 4of the invention is of an illustrative character and is not restrictive and that various changes in design, construction and arrangement of parts may be made Within the spirit and scope of the following claims.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is:
